Yet I can’t tell a minority, gay or transgender to leave my business, can I? See, that’s where your argument falls apart.
Your rights are being violated ... infringed ... trod upon ... by the self appointed leaders of the racial minorities, the sodomites, the perverts, the self-mutilators ... and by the congressthings who pander to such low-life. You have the right to tell them to leave. That right violated by statute.
That said, race is not something one chooses. Race is not a behavior. Sexual perversion is a chosen behavior, but is not necessarily a behavior actually engaged in when one is eating "pizza" (I use the term loosely in this case) at Pizza Hut. So your attempt to equate race, and sexual perversion, with manner of dress in public is mistaken in addition to being irrelevant.
Again, the management and ownership of this Pizza Hut establishment has a right to have, and to enforce, a dress code. And if the rest of us think that their dress code is idiotic we have the right to say so. And we have the right to NOT patronize their establishment. And we have the right to urge others to do likewise.
I wouldn't be caught dead in that joint. The manager is an idiot, and a jerk, and he doesn't deserve my business.
To address your point, though, I'm sick to death of government at all levels sticking its nasty nose and dirty fingers into every aspect of private life. That includes the manner in which private businesses deal with their customers.
If you can't handle that, tough. Learn to live with it.
